Cometic C10348-040 MLX Head Gasket 4.500" Bore .040" Thickness Pair

The Cometic C10348-040 is a pair of premium MLX (Multi-Layer Xtreme) head gaskets engineered for high-performance applications requiring superior sealing and durability. These gaskets feature a 4.500-inch bore with a .040-inch compressed thickness and a 4.515-inch inner diameter for coolant passages.

MLX Technology Advantages:

• Integrated stopper layer provides enhanced combustion chamber sealing and improved clamp load around the cylinder
• Reduces bore distortion compared to traditional gaskets while maintaining superior sealing performance
• Constructed from multiple embossed layers of stainless steel with proprietary high-temperature coatings
• Outer layers coated with Viton to withstand harsh sealing environments and extreme temperatures
• No sealants or re-torque required after installation

Key Features:

• Material: Multi-Layer Steel (MLX) with stopper fold-over layer
• Bore size: 4.500 inches
• Compressed thickness: .040 inches
• Inner diameter (coolant): 4.515 inches
• Quantity: Pair (2 gaskets included)
• Corrosion-resistant stainless steel construction
• Ideal for stock and modified engines

Cometic MLX gaskets are designed to handle extreme cylinder pressures and provide reliable sealing for both aluminum and cast iron applications. The advanced multi-layer construction with Load Control Embossments (LCE) ensures even torque distribution across the sealing surface, preventing fluid leaks and maintaining optimal compression. Made in the USA with American-sourced materials.
